Alternative method to detect compounds produced by Gambierdiscus spp.

Frontiers in Marine Science, 2014
Ciguatoxins (CTXs) and CTX precursors are produced by several Gambierdiscus spp. These polyether toxins are associated to ciguatera fish poisoning (CFP). In addition to CTX, maitotoxins (MTX) and gambierol are also produced by these dinoflagellates.

Toxicity Characterisation of Gambierdiscus Species from the Canary Islands [PDF]

Toxins, 2020
In the last decade, several outbreaks of ciguatera fish poisoning (CFP) have been reported in the Canary Islands (central northeast Atlantic Ocean), confirming ciguatera as an emerging alimentary risk in this region. Five Gambierdiscus species, G. australes, G. excentricus, G. silvae, G. carolinianus and G.

Toxicity and underlying mechanism of the toxic dinoflagellate Gambierdiscus caribaeus to the fish Oryzias melastigma

Ecotoxicology and Environmental Safety, 2022
Gambierdiscus spp. is mainly responsible for the ciguatera fish poisoning (CFP) around the world. The gambiertoxin produced by Gambierdiscus can be passed through the food chain to form ciguatoxins (CTXs) that cause ciguatoxins poisoning.

Asynchrony of Gambierdiscus spp. Abundance and Toxicity in the U.S. Virgin Islands: Implications for Monitoring and Management of Ciguatera

Toxins, 2021
Ciguatera poisoning (CP) poses a significant threat to ecosystem services and fishery resources in coastal communities. The CP-causative ciguatoxins (CTXs) are produced by benthic dinoflagellates including Gambierdiscus and Fukuyoa spp., and enter reef ...

Developing model systems for dinoflagellates in the post‐genomic era

Journal of Phycology, Volume 59, Issue 5, Page 799-808, October 2023., 2023
Abstract Dinoflagellates are a diverse group of eukaryotic microbes that are ubiquitous in aquatic environments. Largely photosynthetic, they encompass symbiotic, parasitic, and free‐living lineages with a broad spectrum of trophism. Many free‐living taxa can produce bioactive secondary metabolites such as biotoxins, some of which cause harmful algal ...

Antibiotics reduce Pocillopora coral‐associated bacteria diversity, decrease holobiont oxygen consumption and activate immune gene expression

Molecular Ecology, Volume 32, Issue 16, Page 4677-4694, August 2023., 2023
Abstract Corals are important models for understanding invertebrate host–microbe interactions; however, to fully discern mechanisms involved in these relationships, experimental approaches for manipulating coral–bacteria associations are needed. Coral‐associated bacteria affect holobiont health via nutrient cycling, metabolic exchanges and pathogen ...

Metabarcoding reveals marked seasonality and a distinctive winter assemblage of dinoflagellates at a coastal LTER site in the Gulf of Naples

Marine Ecology, Volume 44, Issue 3, June 2023., 2023
Abstract Dinoflagellates constitute an abundant and diversified component of marine plankton, mostly associated with stratified conditions typical of late spring through autumn in temperate regions. Yet, difficulties with the identification of many species limit the knowledge of their composition and seasonal succession.

Survey of epiphytic microalgae to evaluate risk of ciguatera fish poisoning across natural and artificial reefs in North Carolina

Frontiers in Marine Science, 2023
Epiphytic microalgae are important contributors to the carbon and nutrient cycles yet are often overlooked during ecological surveys. In reef habitats, epiphytes are often found living on host organisms, including seaweeds or corals, and can influence ...

Volatiles of the Apicomplexan Alga Chromera velia and Associated Bacteria

ChemBioChem, Volume 24, Issue 3, February 1, 2023., 2023
Passing the smell test: The apicomplexan alga Chromera velia harbours a range of bacteria that have been identified by metagenome analysis. Analysis of the volatile organic compounds in the C. velia and individual bacterial isolates showed an almost absent overlap between the released compounds, thus indicating a low contribution of the bacteria to the

Detection of Gambierdiscus and Fukuyoa single cells using recombinase polymerase amplification combined with a sandwich hybridization assay [PDF]

, 2021
Dinoflagellates of the genera Gambierdiscus and Fukuyoa are known to produce several bioactive compounds including the potent neurotoxic ciguatoxins (CTXs) which are able to accumulate in fish and through the food web.
